:provements. in adjustable .ur bjr fsur po relates .particularly tosupports for the persons thereunder.

The 'principalobject of the present invention is the provision o f anumbrella support comprismg vposed in laterally offset relation: to thecentral rod ,of -.-an z'umbifiella, a connecting bar extending betWeen'said-support staff and u mbrella rod, and adjustable means joiningsaidconnecting bar respectively to said support-staff and said umbrella rod,whereby the elevation and angular-ity of the umbrella-relativeto-sai'dsupport staff may be adjusted.

-An'ther object is-the provision'fin an -umbrella support of the classabove described, of end-clamp members for said connecting bareachcomprising a substantially U' shapedin'em'ber adapted to fit around thesupport staff or umbrellajrod for longitudinal slidingmOvementthereQma"boltinterconnecting opposite walls of said clamp andadapted to bring said clamp into gripping engagement with said supportstaif, said bolt also serving as a pivotal support for the adjacent endof said connecting rod, and a clamp bolt spaced apart from said firstnamed bolt and extending through said connecting bar and throughelongated slots formed therefor in said clamp walls.

Other objects are simplicity and economy of construction, ease andconvenience of use, and adaptability to permit folding of the umbrellain the usual manner.

With these objects in View, as well as other objects which will becomeapparent in the course of the specification, reference will be hacl tothe drawing, wherein:

T" e su'pp'o't which'is the subject ofthis'invention comprises essentially a stafi 30 normally displacedlaterally from rod [8, a connecting bar 32 extending between stafi 30and rod I8, and two adjustable clamps 34 and 36 by means of which saidconnecting bar is respectively secured to stall 30 and to rod l8. RodIt! extends just beneath sleeve 26 and there terminates. Thus the areabeneath the central part of the umbrella is left free for the occupancyof persons standing under the umbrella.

, Clamps 34 and 36 are substantially identical except that they arerelatively inverted. Referring principally to clamp 34, it will beseen'that each clamp is formed from a sheet of metal bent tosubstantially U-shape, being'formed to present along its closed edge achannel 38 adapted to fit around staff 30 for longitudinal slidingmovement thereon, and having a pair of substantially parallel side walls40 extending outwardly from said staff.

Connecting bar 32 is tubular, and its end portions 42 are flattened topresent a substantially rectangular cross-section, as best shown in Fig.3. One of said end portions fits snugly between side walls 40 of clamp34, and is pivotallyconnected therebetween by bolt 44, which extendsthrough said side wallsand through a hole 46 provided therefor inconnecting bar end section 42. Said end section 42 is sufiicientlyyielding that when bolt 44 is tightened, side walls 40 of clamp 34 willbe drawn together to clamp channel portion 38 of the clamp 34 firmly onstaff 30.

When the bolts 44 and 48 are loosened, stafl 391.

Theseslots are centered on bolt 44, and permit the connecting bar to pivot 5through a limited are on bolt 44. The connecting: bar may be fixedrelative to the clamps by tightening bolts 48. Clamp 36 is identicalwith clamp 34, except that it is relatively inverted and the" channelportion 38 thereof fits around central rod I8 01 the umbrella.

Thus by loosening bolts 44 and 48, the elevation of umbrella in may bevaried simply by changing"""' and connecting bar 32 may be brought intoap'-"-- proximate axial alignment with umbrella rod [8, i as shown in Fi2, and hence the support does}; not interfere substantially with thenormal fold-,

ing of the umbrella as shown.
